Xander finds out he's half incubus and begins to unlock his hidden bloodline, getting any and every girl he so desired, up to and including the slayer herself, not to mention keeping his other eye intact would be nice. Discovering with his new blood, that any woman he nails is forever his.
In the future, turns willow into a sex slave and has her send him back so he can finally get everything he's always wanted.
It makes so much sense. How did no one see it before, the way girls flocked to you, even those who hated you couldn't resist. Even I, a lesbian, almost fell for you back then, and I guess now I ultimately did, though I tried to use Oz to get over you, only to finally decide I should just go full Lesbo if I couldn't have you. It also explains why the love spell went out of control; it must have fused with your natural sex magic.
He snorts, all except the one I wanted.
Well, let's not forget she's the slayer; she'd have a higher resistance than most, and you weren't even fully awakened back then. I'm sure things would be different now.

I was only ever funny to hide how weak and pathetic I was, and now I'm not.
True, about being weak, but you were never pathetic, not to me at least.

Eventually becoming the entire gang's stress relief.

The Wish
Cordelia, hateful and envious of Buffy's life, especially when she took the best guy around, the MC, the guy she wanted, she makes the wish.
Anya, who has to stick around to feed off the residual energy created from the wish, decides to take the MC for a spin, after all, if he was good enough for the slayer, he was likely good enough for her.
Cordelia, scared and confused in the vampire-ruled world, slowly figures out what's going on and is sad to learn the guy she wanted still isn't with her, even without Buffy around. Angrily discovers Anya with him, gets the necklace, and sets things right.
Anya, having fallen for MC, manages to harness just enough of the escaping power to make a small change to the true world.
Now Buffy accepts Anya into their relationship with little resistance, and in the future, Faith joins, thanks to Buffy's confusing feelings towards the pull of their slayer powers and Anya's change to her human relationship morality, much to Anya's chagrin at now having to share with not just one, but two others. However, she grows to like how they can also give her orgasms.
And MC is sitting happily, enjoying it all.

Proceeds to convince her that she's the true slayer, the chosen one, and that Buffy should be dead, how she never should have been revived, how she came back wrong, even more so the second time.
How apocalypses are supposed to be rare, and the only way the world could ever get a rest is to put Buffy and all her friends down.
Helps her kill Buffy and all her friends and fix the balance.
.
Or a possible twist ending where faith betrays him to save Buffy to be a better person.
He's as shocked as she is when she backstabs him and plants the knife into him.
"You betrayed me?" he asks, eyes wide with disbelief.
shes whinces, "Yeah, I guess I did."
"And to think I was just starting to fall for you," he says, appearing to be on the edge of death.
All she could do was apologize, with teary eyes, "I'm sorry."
"So am I," he says as he moves his arm with newfound life, his hand clamping over her throat.
"Faith!" cries a wounded Buffy, rushing to her aid, just as he snaps her neck and drops her body like trash.
"You'll pay for that!" shouted Buffy angrily.
"And you're next," he said, walking towards her.

After Angel loses his soul the first time, another floating in the void seizes his chance to take over before Angelus, wiping out the demon and making the new body his.
Proceeds to rock Buffy's world the following day, continuing the relationship.
Maybe in the future they finally find out when Anya turns back into a vengeance demon, but it's far too late and no longer matters as Buffy has fallen even harder for the new imposter in Angel's body, and at this point knows him far better for far longer.

Buffy the Vampire Slayer -
During a truth spell botchery by Willow, Spike finds himself telling Buffy far more than he ever would have.
"You can't love me Spike, you don't have a soul."
Spike pushes her against the wall angrily, "Let me tell you something slayer. There ain't no one in the world that loves harder or longer than me, just ask my ex, over a century and not once did I ever cheat on her despite what she did to me."
"Wish I was like you lot, wish I could hate, but I was never really built for that."
Buffy shakes her head, "No, you're an evil vampire."
Spike growls, "News flash luv, everyone's evil. The vampire doesn't make you a different person, end of. The only reason vampires happen to kill more than the regular bloke is because they need to feed, soul be damned, it doesn't mean anything."
Buffy, "No, you're wrong, you're forgetting about Angel."
Spike snorts, "Don't make me laugh, you didn't fall in love with Angel, you fell in love with a curse, basically something not even real. Anybody would turn good if you cursed them to feel guilty all the time... Trust me, slayer, I'd still be the same soul or not as would any vampire, and if you don't believe me, go ahead and remove the curse on angel and find a way to permanently soul him without it, see what happens."
.
"And let's not forget how that cowardly fuck sat back and let you die, whereas I would have been fighting right by your side." Spike
"I went on my own at first, but he came later with Xander," Buffy argued desperately. "Saved my life in the end."
Spike retorted, "I heard it was the little twerp who gave you CPR. Tell me where the great annoying one was then?"
"Well, he couldn't do it because vampires don't have breath, but he led Xander to me," said Buffy.
Then Spike looked at her like she was the dumbest person he's ever met as he quickly took out and lit a cigarette, blowing the smoke in her face.
Spike sighed for her, "He lied luv."
"No, you're wrong," she runs away with tears in her eyes as the reality of the smoke hits her.
...
During a Scooby Gang meeting at Giles, Xander once more insults and threatens Spike with needing a good dusting.
Spike's eyes narrow dangerously as he sits up, "One more word whelp, and I'll come over there and..."
"And what chip boy? what are you going to do?" asked Xander confidently, knowing Spike couldn't do any real harm to him.
Both ignoring Buffy's warning, "Spike! Xander!"
Then Spike grinned in a way that made the hairs on Xander's neck stand.
"I'll kiss you, with tongue," stated Spike, acting like he meant it.
Shocking the room as mouths fell open and Xander visibly paled, not expecting such a threat.
"You, you wouldn't dare!" exclaimed Xander shakily as he quickly maneuvered behind Buffy.
"Count on it fuck boy, you'll find vampires are very open-minded," said Spike with a leering grin.
"Hey, get your own, Xander's my fuck boy," said Anya, pulling a very scared Xander back towards her.
A bemused Buffy tried not to laugh as she spoke up once more, cutting through the silence, "Xander, stop provoking Spike, and Spike stop threat... Scaring Xander," she said, nearly snickering at the end.
A furiously blushing Willow is squeezing Tara's hand in the background.
And Giles sighed as he took off his glasses and began cleaning them absentmindedly, cursing his life choices to be stuck in a room with children.
_________________________
Buffy the Vampire Slayer -
Spike is the unmatched vampire he was always meant to be, the slayer of slayers.
Balance means the good guys don't always win.
.
When Spike gets the ring of amara, it not only makes him invincible, but it also breaks the many curses holding him back. Curses like making him obsessed over Slayers when all he wants is a good fight, regardless of who gives it to him. Another Curse that prevents him from harming Buffy in any significant way, like killing her friends and such.
Also ends up later falling for Anya, someone who wouldn't cheat on him, helping break the curse/punishment by her old boss that made her fall for Xander, a complete loser that was completely unworthy of her.
Spike tells her so, why would you fall for a loser who's barely over a decade old whose already cheated, over someone who has over a century of faithfulness?
Xander says something like really, you're going with this disgusting evil demon. causing Anya to frown.
Anya says you're right and then walks out with a smug-looking Spike after he backhands Xander to the floor, leaving him whimpering in pain.
Eventually helps Anya regain her powers, and they become the demon power couple everyone fears.
Eventually, Spike kills everyone except Glinda, aka Tara, and Faith, aka the true slayer, before deciding he's done and leaves happily ever after with Anya.
